1989 Honda Civic Car Sat up for a while

Hello, I wanted to know if you could assist me in getting my car running. I had this car outside and it would crank, I just had body damage. I let it sit for a while because I lost the keys and now it will not say anything. I replace the battery, because it was completley drained and now the lights, radio etc come on. When pressing in the clutch to start the car, once again it says nothing.

I hope that the motor has not lock up and now I will not be able to get it up and running.

thanks in advance for your support
